Jerky transmission shifting

Question by Clark418 posted 8 months ago in 2010-2016 (W212)

I recently had the valve body replaced in my 2010 MB E350.  I now sometimes feel a slight jerk when it shifts.  The mechanic told me it was programmed for a hard acceleration and will adjust to my driving habits in about a month.  Is he putting me off, or will it adjust?  It is a problem I need to address immediately?
